Definitions

  • the invention relates to a device for controlling a motor vehicle gearbox.
  • the invention relates more particularly to a device for controlling a gearbox of a motor vehicle, of the type comprising a gear shift lever pivoting about a first axis on a support pivoting relative to the vehicle around a second axis , orthogonal to the first axis, and connected to two members for transmitting the movements of the lever in the direction of the gearbox.
  • Such a device has already been described and shown in the document FR-A-2,689,460, and is in particular used to control a gearbox using two sheathed cables.
  • the purpose of the device is therefore to transmit the movements from the upper end of the gearshift lever which is arranged inside the passenger compartment to the gearbox so as to allow the selection and engagement of the different gear ratios.
  • the two axes of articulation of the lever on the support and of pivoting of the support on the frame are concurrent and the lever is arranged substantially perpendicular to these two axes.
  • the entire gearbox control device which is a relatively heavy welded structure, is then found substantially at the level of the driver and passenger knees which, in the event of an accident, may be harmful to their safety.
  • the driver is required to exert a vertical force upwards or downwards, rather than a horizontal force forwards or backwards.
  • tilting the lever backwards implies a greater angle of fracture of the driver's wrist, which quickly proves to be painful.
  • the object of the invention is therefore to propose a device for controlling a gearbox which enables the frame of the device to be carried forward while retaining a substantially horizontal trajectory at the upper end of the gearshift lever and ergonomically favorable.
  • the invention provides a device of the type seen above, characterized in that the lever and the support are connected by two links so as to form with them a deformable quadrilateral, the ends of the two transmission members being connected respectively to one of the links and to the pivoting support.
  • Figures 1, 2 and 3 show a preferred embodiment of a cable control device of a gearbox according to the teachings of the invention.
  • the device 10 is fixed to the vehicle body (not shown) by a frame 12 which mainly comprises a horizontal base 14 for fixing and vertical parallel uprights 16.
  • the two uprights 16 are each pierced with a hole 18 with a substantially horizontal longitudinal axis A1.
  • the holes 18 are intended to receive a bolt 19 acting as a pivot shaft for a pivoting support 20.
  • the pivoting support 20 comprises a tubular pivot body 22 traversed by the pivot shaft 19, received between the two uprights 16 and on which is welded a longitudinal vertical plate 24 which supports two articulation sleeves 26, 28 with respective transverse axes A3, A4.
  • transverse sleeves 26, 28 are therefore capable of pivoting with the support 20 around the longitudinal axis A1.
  • Two rods, respectively upper 30 and lower 32 are articulated on the support 20 around the respective axes A3 and A4 by means of rods 27, 29 received in the articulation sleeves 26, 28.
  • the rods 30, 32 extend longitudinally towards the rear when considering the figures and carry at their respective rear ends 34, 36 hinge shafts 38, 40 with respective transverse axes A5, A6.
  • Two sleeves 42, 44 are rotatably mounted on the articulation shafts 38, 40 around the respective transverse axes A5, A6 parallel to the axes A3 and A4.
  • a speed change lever 46 is fixed by welding to each of the two sleeves 42, 44 and it extends in a longitudinal vertical plane P which substantially contains the axis A1.
  • the lever 46 is inclined towards the rear and carries at its upper end 48 an operating knob 50.
  • the vertical plate 24 of the support 20, the two links 30, 32 and the lever 46 form a quadrilateral articulated at its four vertices around the axes A3, A4, A5 and A6.
  • the assembly being linked to the pivoting support 20, it can pivot around the axis A1.
  • two cables 52, 54 are provided. the first of which is articulated at the free end 56 of an extension 57 of the lower link 32 which extends longitudinally in front of its axis A4 of articulation on the support 20.
  • the first cable 52 makes it possible to transmit the movements of the lever 46 in a longitudinal plane towards the gearbox.
  • the second cable 54 is hooked to the end of a transverse arm 58 which is fixed on the pivoting support 20.
  • the transverse arm 58 makes it possible to transmit, in the direction of the gearbox, the movements of the lever 46 in a transverse plane.
  • the control device 10 shown in the figures being a device intended to be installed on the dashboard of a vehicle, that is to say substantially vertical to the engine compartment, the outlet of the sheathed cables 52, 54 is laid vertically.
  • sheaths 60, 61 of the cables 52, 54 are provided to bear against a lower face 62 of the base 14 of the frame 12 of the device 10.
  • FIGS. 4A, 4B, 4C and 5A, 5B, 5C show diagrammatically the operation of a device according to the invention.
  • FIG. 4A the device is shown in neutral, seen from the side, and there is seen the lever 46 which is articulated by means of the two links 30, 32 on the pivoting support 20.
  • Point I intersection of the straight line D, perpendicular common in the plane P to the axes A3, A5 of articulation of the link 30 with the straight line D ', perpendicular common in the plane P to the axes A4, A6 of the link 32, represents the instantaneous center of rotation of the movement of the lever 46 relative to the frame 10 in the plane P.
  • the instantaneous center of rotation I is located substantially vertical to the knob 50 arranged at the upper end 48 of the lever 46 so that the trajectory of the knob 50 of the lever 46 is substantially horizontal.
  • the device 10 transforms the essentially longitudinal movement of the knob 50 into an essentially vertical displacement of the end 56 of the lower link 32 to which the cable 52 is hung.
  • FIGS. 5A, 5B, 5C the various selection positions of the lever 46 are shown in a transverse plane.
  • the transverse arm 58 is fixed on the pivoting support 20 so that, when the knob 50 is maneuvered in a transverse direction, the lever 46 causes the support 20 to pivot around its axis A1 which carries with it the transverse arm 58, the l the free end describes a vertical trajectory which is transmitted to the gearbox by the cable 54.
  • the support 20 pivots around its axis A1.
  • the lower link 32 being arranged in the longitudinal plane P which contains the axis A1 and being located at a very short distance from the axis A1, its displacement is of very small amplitude and takes place moreover perpendicular to the direction of the cable 52 so that no movement is transmitted by cable 52 to the gearbox.
  • the support 20 When the driver engages a gear by maneuvering the knob 50 in a longitudinal direction, the support 20 remains in its previous position and there is therefore no movement either of the transverse arm 58, or of the cable 54 which is attached to it.
